concrete-bolt-2844

When last you saw my cast bolt it was made from plaster and an ABS 3D print which served as a mold. It sort of worked. As mentioned, it was more “art object” than “functional thing” and that was what I was going for…

Well, I made another ABS mold from the first experiment and even though I had worked with a flexible filament mold I thought I would give the ABS version one more try, this time with concrete instead of plaster.

I really liked the way this one turned out. Yes, I had to destroy the mold again, and in the process the part got damaged and broken, and then I pulled out the hot glue gun and put it back together, and now I like it even more!

It’s one of those situations where things go wrong so you just do something and it turns out (possibly) better than you thought it would. I joked that this was the modern maker equivalent to Kintsugi, using hot glue instead of gold.

I really like how it has this feel of being an ancient relic. In a strange twist of fate, I was at first annoyed with all the tiny pebbles in the concrete, so much so that I made a sifter to remove them, but now I’m thinking up a list of things I can mix into the concrete besides pebbles (and, probably pebbles too.)
